PAM-XIAMEN Offers AlGaInAs epitaxial wafer for Laser diode

2018-03-02

Xiamen Powerway Advanced Material Co.,Ltd., a leading supplier of Laser diode epitaxial structure and other related products and services announced the new availability of size 3” is on mass production in 2017. This new product represents a natural addition to PAM-XIAMEN's product line.

Dr. Shaka, said, "We are pleased to offer Laser diode epitaxial structure to our customers including many who are developing better and more reliable for DPSS laser. Our Laser diode epitaxial structure has excellent properties, tailored doping profile for low absorpton losses and highpower single mode operation, optimized active region for 100% internal quantum efficiency, special broad waveguide (BWG) design for high power operation and/or low emission divergence for effective fiber coupling. The availability improve boule growth and wafering processes." and "Our customers can now benefit from the increased device yield expected when developing advanced transistors on a square substrate. Our Laser diode epitaxial structure are natural by products of our ongoing efforts, currently we are devoted to continuously develop more reliable products."

PAM-XIAMEN's improved Laser diode epitaxial structure product line has benefited from strong tech, support from Native University and Laboratory Center.

The laser diode epitaxial structure is grown using one of the crystal growth techniques, usually starting from an N doped substrate, and growing the I doped active layer, by the P doped cladding, and a contact layer. The active layer most often consists of quantum wells, which provide lower threshold current and higher efficiency.
